checkpatch: update suggested printk conversions
Direct conversion of printk(KERN_<LEVEL>... to pr_<level> isn't the
preferred conversion when a struct net_device or struct device is
available.
Hint that using netdev_<level> or dev_<level> is preferred to using
pr_<level>. Add netdev_dbg and dev_dbg variants too.
Miscellaneous whitespace neatening of a misplaced close brace.
